It started with an App that residents could download to report locations where sidewalks needed repair. The city sorted out those reports and ranked them in a database, which repair crews used to prioritize their work.

Carter's group has moved away from the model common to many smart city initiatives of letting tech-savvy(精通技术的）residents drive the process. Instead, they run meetings to find out what problems people in different neighborhoods care about solving.
